PHOENIX — Permanent repairs to a section of US 89 north of Flagstaff is set to begin after remnants of Hurricane Rosa damaged the roadway in 2018, the Arizona Department of Transportation announced Monday.

Emergency repairs were conducted on the 30-foot section of the highway four miles north of Cameron less than 48 hours after the storm washed the road out, according to a press release.

The long-term repairs will reconstruct that segment of US 89, improve the drainage system in the area and remove an old abandoned bridge.

It is expected to be completed by the fall and cost $1.7 million, according to the release.

Traffic will continue in both directions throughout most of the project, the release said, but there may be times the highway will be restricted to one lane with a temporary traffic signal to direct drivers through the work zone.

US 89 is an important corridor to attractions in the northern part of the state including the Grand Canyon, Lake Powell and Monument Valley.

ADOT personnel from neighboring cities and towns had to haul in and compact 500 cubic yards of material to restore the base following the storm and put down 120 tons of asphalt pavement, according to the release.

Along with heavy precipitation in northern Arizona, remnants of Hurricane Rosa also dropped between one to three inches of rain across the Valley on Oct. 2, 2018, which was the wettest October day in Valley history.
